Testimonies are assets in prayers that authenticate the reality of what God will do in your life. The power of testimonies put you above your problems and destroys all lies and deceits of the devil concerning all that the Almighty God has promised you.
"Thy testimonies have I taken as an heritage for ever: for they are the rejoicing of my heart"
Psalms 119:111

Those who give testimonies of what God does in their lives are committing God into sustaining what He has done. It is through the power of your testimony that your miracle becomes permanent. I decree that the Almighty God will do something great in your life that can never be hidden in Jesus' name.
You need faith to receive all that God has promised, and one of the ways to bring those promises to fulfilment is by testifying of the goodness of the Lord. It is by faith that you receive boldness to come before the presence of the Almighty God to access your rightful blessings. All those who have done great things are people who are given to testifying of the deeds of God in their lives so that others can also 'key' into their encounters. David defeated Goliath before the physical battle by the word of testimony. He knew that by his experience and age, he was not fit enough to confront Goliath in a physical battle. Goliath cursed him, and he also cursed Goliath by the name of his God and that same God gave him the victory he testified about. When you come face to face with situations and circumstances that are beyond you, remember that there is a God that will never leave you nor forsake you. All you need to do is believe His plans for you and live it while waiting for it to come to pass. When battles rise against you, remind God of all His acts in your life and in the lives of others before now. You can be sure that He can repeat in your life whatever He has done for someone. If your medical report is not favourable, remember there is a God who has over turned the medical report of more critical situations and believe that yours will not be impossible for Him to do. When you remind God of all that He has done in the past, you are invoking His faithfulness and compelling Him to reproduce the act.
The people that know their God shall be strong and they shall do exploits. With the power of testimony, it becomes very easy to do great exploit. All you have to do is to know the God you serve. David knew the God he was serving. Daniel knew the God he was serving. Elijah knew the God he was serving. Esther knew the God she was serving. Joshua knew the God he was serving and he declared boldly that he was not among those who saw themselves as grasshoppers. He knew through the acts of His God that they were more than able to possess the Land and enter into their promised destiny. You must not be afraid to dominate. You must see yourself as a champion who is triumphant. Your faith in His promises must never be shaken. You carry divinity and there is nothing in life that can conquer you. I decree that your testimonies shall overflow in Jesus' name. Written by Pastor E.A. Adeboye.
